(ci. iss-s4) Our invention relates to locomotives and has among its objects and advantages the provision voi' an'improved cab window.

In the accompanying drawing:

Fig. 5 is a sectional view along the line 8 8 of Fig. 4; and

lFig. 6 is a fragmentary perspective view of our window.

In the embodiment selected to illustrate our invention, we make use of a locomotive cab I0 including a conventional door I2 which is located on the forward wall of'the cab and may be opened and closed in any conventional manner. 'I'he door I2 includes a frame I4 and glass panes I8 and I8. These panes are iixedly carried by 4the frame. Our window is indicated generally at 28 in Fig. l.

Specifically, our window comprises a. frame 22 having its verticalV reaches 24 tting snugly within the frame I4 (see Fig. 4). Lugs 26 are formed integrally with the frame 22 and are arranged in overlapping relation with the inner faces of the frame I4 and secured thereto by bolts 28. In Fig. 4, we illustrate the panes I8 and I8 as having overlapping relation at 30 with`the horizontal reaches 32 oi' the frame 22, the margins of which panes may be rendered weather-prooi by putty 34 Within'the frame 22 we mount an inner frame 38 which includes vertical reaches 38 having anguiar faces 40 arranged in wedging relation with corresponding angular faces 42 on the vertical reaches. of the outer frame. The lower horizontal'reach 32 of the frame 22 is provided with -an angular facef44' having wedging relation with the corresponding angular-'tace 48 on the lower horizontal reach 48 oi' the frame 38. Such wedging relation establishes a weather-prooi joint be tween rthe contacting faces of the two frames.

In. Fig. 4, we illustrate the upper horizontal reach 48 of the frame 38 as being provided with a wall 68 lying in abutting relation with a rib 52y depending from the upper horizontal reach 32 oi' the frame 22. The frame 88 carries two lugs 84 whichloosely receive a shaft-.68 having its ends journaled in the vertical reaches 24 of the frame 22 (see Figs. 4 and 5). Thus, the frame 38 is hingedly connected with the frame 22 and may be pivoted outwardly to an open position about the shaft 56 as an axis. A quadrant 88 5 has one end connected with an extension 8i) projecting from the frame 38. This end of the quadrant is bored i'or the reception of a screw 82 having threaded relation with the extension 68, which screw` includes a, shoulder 64 having abutting rel0 lation with the extension so as to provide free pivotal action for the connected end of the quadrant. In Fig. 3, we illustrate the quadrant as extending through an opening 88 in one of the frame reaches I4 and through an aligned open- 15 ing 88 in a lug 10 projecting laterally from one of the vertical reaches 24'. The lug 10 terminates in an ear 12 which carries a set screw 14 for xedly securing the quadrant at various adjusted positions. In Fig. 4, the lug 18 is illustrated as 20 being provided with a fixed tooth 18 arranged to receive the notches 'I8 whereby the weight of the window in its adjusted position may be carried by the tooth `18 and the set screw 14 utilized' for holding the tooth in operative relation with one 5 of the recesses 18.

All the reaches 38, 48 and 49 of the frame 36 are provided with inwardly extending flanges 88 vagainst, which we place an outer glass pane 82. This pane is urged against the flanges 80 by a 80 pressure frame 84 which is positioned inside the frame 38. In Fig. 4, we illustrate the lower reach of the pressure frame 84 as being positioned within a ange 88 carried by the reach 48. The flange is so positioned as to hold the frame 80 in 35 firm relation with the pin 82. The upper reach of the frame 84 is held in place by means of a wing nut 88 having a ange 90 arranged in slight overlapping relation with the frame. 'Ihe wing nut 88 has threaded relation with a stud 92 an- 40 chored in the reach 49.

The pressure frame 84 may be removed by merely unscrewing the wing nut 88 and pushing the upper part of the frame inwardly of the cab HI. After the upper part of the frame has been 45 moved slightly, the lower part of the frame may bellifted out of holding relation with the flange 88. An inner glass pane 94 is mounted within the pressure flrame84. The latter is provided withfianges 98 against which the pane -94 is urged 50 by means of bowed flat springs 98. The ends of the springs project Vthrough slots IIII) in the upper and lower horizontal reaches 98 of the pressure trame 84, and the ends of the springs are arranged in abutting relation with the reaches 48 and 49 so as to be supported in bowed relation and in pressure contact with the pane 94. We arrange the springs 98 to lie within the margins of the vertical flanges 96 in the pressure frame 84, thus being located out of sight obstructing relation with the pane 94.

Fig. 3 illustrates one of the vertical reaches of the pressure frame 84'as being provided with a slot |02 through which the pane 94 may be pushed for assembly purposes.

The glass panes 82 and 94 -are arranged in spaced relationl and cooperate to provide an efcient storm window. The air space operates to prevent frosting of the glass so that clear vision may be had. To cooperate with the air space in maintaining clear vision we mount an electrically heated element |04 between the glass panes 82 and 94. In Fig. 5, we illustrate the heating element as extending vertically along the two vertical reaches of the pressure frame 84 and horizontally along its lower horizontal reach.

One end of the heating element is connected with a screw |06 which is grounded to the locomotive, andthe heating element passes through insulating bushings |08 carried by supports ||0 hooked over the cut away corners ||2 of the pressure frame. The opposite end of the heating element is connected with -a shaft ||4 (see Fig. 4), which shaft is supported within an insulating bushing H6 mounted within an opening in the upper ange of the pressure frame 0d. The outer may be connected with the electric circuit of the locomotive. Since the motor |26 may be of conventional design, no further description thereof is required. We show the motoras being secured in position by means of screws |30 which have threaded relation; with the frame 22. The motor |26 is connected with the oscillating shaft |32 which is rotatably mounted in an opening in the frame 22. To the end ofthe shaft |32 we connect a conventional wind shield wiper |34 which is arranged to sweep back and forth upon the outer face of ,the glass pane 02.

A'trough. |36 'is carried by the reach 48, which trough xsfelevated'intermediatepof its ends, as

indicated at |30 in Fig. 1 for deecting water running therein to the sides of the door I2.

Our invention embodies a storm window which may easily be connected with a locomotive cab door, which. storm window operates to provide clear vision for the occupants of the cab under 'i all conditions of service. In the closed position of the storm window an effective weather-tight condition is attained, but the storm window may be adjusted to various open positions and secured in such positions of adjustment through the medium of the quadrant 58. The wiper |34 operates to sweep oi any accumulation of snow or heavy rain which might otherwise obstruct clear vision, while the spaced panes and the heating device operate to prevent frosting of the window. The'electrical facilities may-be connected with the electric circuit of the locomotive.

Without further'elaboration, the foregoing will so fully explain our invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

We claim:

In a device of the type described, a frame having flanges, atransparent pane positioned adjacent said anges, a pressure frame positioned inside said first frame and bearing against said pane, a second pane mounted on said pressure frame, and resilient means cooperating with said second frame and said second pane for holding the latter in position, said panes being spaced, to provide an air space.
